The document outlines steps for assessing an organization's application portfolio for migration to the cloud, including conducting discovery workshops, interviewing application owners, implementing discovery tools, profiling applications, identifying complexity and priorities, and developing a migration roadmap. It also discusses criteria for segmenting and prioritizing applications, different application disposition options, and patterns for actual application migration.
